Why the hell does Doom Island catch fire when it crashes down? It's an ISLAND with a CASTLE on it O_o

Well, it is an island, and islands sometimes have trees. If you really want to get technical perhaps the island was falling so fast that the friction of the atmosphere burns it (aka Meteor effect). Or perhaps it was caused by the eruption of energies clashing between the Sinistrals and Maxim's party.

Why did I answer this question? Because who cares! *dances* Doom Island, Doom Island, Doom Island is on FIRE. We don't need no water let the bad boy burn!

This might not be a stupid Lufia question because its apparent in most RPG's. But I just had to ask. Why is it that characters are bigger than the boats?

I understand it on the world map, but when you're Shaia lab and Falcon is as big as your washtub... It just doesn't make sense.
